Application filed September 6, 1905. Serial No. 277,252.

To aZZ whom it may concern.-

Be it known that I, JOHN LARSEN, a citizen of the United States,residing at Burntranch, in the county of Trinity and State ofCalifornia, have invented a new and useful Hydraulic Mining Apparatus,of which the following is a specification.

This invention relates to hydraulic mining apparatus, and has for itsobject to provide improved means for shifting the nozzle in a simple andeflicient manner. In this connection it is proposed to provide a novelform of deflector which is controllable by hand and is arranged to makeuse of the force of the stream passing through the nozzle to shift thelatter in any direction, and thereby avoid manual shifting of thenozzle.

With these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed out in the appended claims.

In the drawings, Figure 1 is a longitudinal sectional view of a nozzlefor hydraulic mining involving the principles of the present invention.Fig. 2 is a front view thereof. Fig. 3 is a side elevation, on a smallscale, of a hydraulic giant equipped with the deflector of the presentinvention.

Like characters of reference designate corresponding parts in allfigures of the drawings.

In explanation of the present invention there has been shown in theaccompanying drawings the nozzle 1 of the discharge-pipe of a hydraulicmining apparatus which is swiveled to swing in any direction upon thesupply-pipe 2 in any suitable or approved manner, as shown in Fig. 3 ofthe drawings. A tubular deflector 3 is associated with the nozzle and isprovided at its rear end with a substantially semispherical flange 3which has a working fit within a substantially semispherical member 4,the latter being connected to the nozzle 1as, for instance, by beingthreaded to an annular flange or collar 5, provided upon the extremityof the nozzle 1. If desired, the flange or enlargement 5 may be formedas an integral part of the nozzle, or it may be in the nature of a ringor collar threaded thereon, as indi cated in the drawings. When thecoupling member 4 is threaded upon the part 5, it is preferably providedwith a of cars or projections 6 for engagement y a spanner to enable theconvenient application of the member 4 with respect to the flange 5. Theengaging faces of the parts 3 and 4 are ground, so as to have a snugworking fit, and thereby produce a water-tight joint between the memberswithout requiring the employment of packing.

For the manual control of the deflector there is provided a handle orcontrolling element 7, which is provided at its outer end with a loop orring 8, disposed at substantially right angles to the handle-bar 7 andarranged to embrace the deflector, whereby the latter may be tilted inany direction upon the member 4 by manipulation of the handle 7. Forconvenience in assembling and removing the handle it is proposed toprovide the deflector with diametrically opposite external lugs or ears9, which are provided in their outer ends with transverse seats orgrooves 10 for the reception of the ring 8, the latter being providedwith diametrically opposite outwardly-extending seats or recesses 11,designed to receive the projections 9, as shown in Fig. 2 of thedrawings, when applying and removing the handle, the ring of coursebeing turned so as to disaline its seats and the projections 9,whereupon the ring will be fitted in the grooves or seats 10, andthereby held against lateral displacement along the deflector.

In practice when it is desired to change the direction of the streamissuing from the nozzle the handle 7 is manipulated to tilt thedeflector in the desired direction upon its universal connection withthe nozzle 1, whereupon the force of the stream against that side of thedeflector which is inclined across the end of the nozzle tends to swingthe nozzle slowly to the right or the left upon its swiveled connectionwith the supply-pipe 2 until it has assumed the desired position, andthen the handle is released, and the force of the water will return thedeflector into longitudinal alinement with the nozzle. The advantage ofthis feature is that it employs the force of the water, rather thanmanual force, to shift the nozzle from the right to the left, and asthis shifting is comparatively slow it prevents the sudden changing ofthe direction of the stream. The direction of the nozzle may be changedvertically by vertically tilting the deflector and the direction of thestream may be changed horizontally by horizontally tilting thedeflector.

Attention is directed to the fact that the member 4 is removable fromthe nozzle 1,

and the member 3 is removable rearwardly through the member 4:, wherebythese members may be removed and another member 3 of a diflerentdiameter assembled with the member 4 and then connected, through themedium of the latter, to the nozzle 1. By this arrangement of parts thediameter of the stream issuing from the nozzle may be changed to suitvarious conditions without replacing the entire nozzle.

The particular advantage of the ball-andsocket connection between thenozzle 1 and the deflector 3 resides in the fact that a water-tightjoint is provided, and there are no sockets or recesseswherein dirt andthe like may accumulate and interfere with the ad justment of thedeflector.

Having thus described the invention, what is claimed is- 1. Thecombination with the nozzle of a hydraulic mining apparatus, of atubular deflector having a swinging connection with the nozzle andprovided with external projections, and a controlling-handle having aloop embracing the deflector back of the projec tions, the loop beingprovided with internal seats capable of alinement with the projectionsto permit application and removal of the loop.

2. The combination with the nozzle of a hydraulic mining apparatus, ofatubular defiector having a swinging connection with the nozzle andprovided with external projections, said projections having transverserecesses in their outer ends, and a controllinghandle having a loopembracing the deflector and received within the recesses of the projections, the loop being provided with internal seats to pass over theprojections when applying and removing the loop.

In testimony that I claim the foregoing as my own I have hereto afliXedmy signature in the presence of two witnesses.

JOHN LARSEN.
